Calculate the sum of the product of the number of molecules (Ni) and the mass of each molecule (Mi) for all data points. Step 1 Calculate the molecular weight (number average). MW―n=f1+f2+f3+f4f1M1+f2M2+f3M3+f4M4=0.20+0.30+0.30+0.200.20...
Calculate the density of UO2. Dry air at STP has a density of 1.2929 g/L. Calculate the average molecular weight of air from the density. Calculate the density of oxygen, O2, under each of the following conditions: STP, 1.00 atm, and 35.0 degrees C. ...
The modern chocolate industry is worth more than 100 billion dollars a year worldwide, and it's showing no signs of slowing down. What used to be a rare luxury is now a staple part of the average person's diet, either as an indulgent snack, or in its purest form, as a health food...
The simple average molecular weight of the 20 common amino acids is 138, but most biochemists use 110 when estimating the number of amino acids in a protein of known molecular weight. Why is this? Create a 1700 calorie diet using the food pyramid. ...
Nitrogen has a molecular weight of 14 so a N2molecule has a molecular weight of 28. Oxygen has a molecular weight of 16 so an O2molecule has a molecular weight of 32. Given the mixture of gases found in air the average molecular weight of air is around 29. Water is made up of two...
No matter how large or small the molecule, the procedure for calculating its molecular mass is the same. You look up the atomic mass of each of the elements in the formula, multiply it by the number of atoms of that element in the compound and add it to all the others. This gives yo...
A computer programm for the desk-top calculator HP 9810A to analyse sedimentation profiles and to calculate the weight average (Mw) and the number-average molecular weight (Mn) of DNA as well as of their breakage parameters (Nw andNn) is... HW Jank,J Hofemeister - 《Die Kulturpflanze》...
I do have a question: average adult needs 270 g of carbohydrate daily, I assume that is net carb. In order to get 270 g of carb for my energy need, I would need to eat more then 270 g of total carb, depending on how much fiber I consume, and etc. Is that correct? I am ...
The molar mass of any solid, liquid, or gaseous substance is the number of grams of the substance in its molecular (molar) form that contains 6.0221367 X e^23 atoms of the substance (Avogadro's Number). This is because the mass of a substance is dependent on the molecular weight of the...
For cyclists, zone 2 training falls in the range of 55% to 75% of their Functional Threshold Power (which is the highest average power you can sustain for one hour, measured in watts). But you don’t need to be a seasoned cyclist to make use of this mode of training – hop on a...
